Trading Authorization

Building on the concept of discretionary authority, this section covers the formal documents that grant third parties the right to enter orders in a customer's account and the fiduciary obligations that come with certain account types.


Types of Trading Authorizations

A trading authorization (also called a power of attorney) is a written document that grants a third party the right to enter orders in a customer's account.

TypeAuthority Granted
Full (unlimited) trading authorizationThe authorized party may buy, sell, and withdraw cash or securities from the account
Limited trading authorizationThe authorized party may buy and sell securities but may not withdraw cash or securities from the account

Think of it this way: The key difference is withdrawal rights. A limited authorization lets someone trade for you. A full authorization lets someone trade and take money out.

Discretionary authority is a form of trading authorization that specifically authorizes the agent to choose the security, amount, or action without the client's prior consent on each trade.


Third-Party Trading Authorization

A customer may grant trading authorization to a third party (e.g., a spouse, attorney, or investment adviser) by signing a written power of attorney.

Requirements:

  • The broker-dealer must have a copy of the trading authorization on file
  • The third party must be identified on the account records
  • The broker-dealer retains the right to refuse to accept a trading authorization or to restrict the scope of activity permitted under it

Fiduciary Accounts

Certain accounts are inherently fiduciary in nature; the person directing the account has a legal duty to act in the best interest of the beneficiary:

Account TypeWho Has AuthorityBeneficiary
Trust accountTrusteeTrust beneficiaries
Estate accountExecutor or administratorDeceased's heirs/estate
Custodial account (Uniform Gifts to Minors Act / Uniform Transfers to Minors Act)CustodianMinor
Guardian accountCourt-appointed guardianIncapacitated person

In all fiduciary accounts:

  • The person with authority must act in the best interest of the beneficiary, not for personal gain
  • Fiduciary accounts are subject to the applicable standard of care (covered in the next section)

Exam Tip: Gotchas

All fiduciary account types share the same core obligation: act in the beneficiary's best interest. The exam may test whether you can identify which accounts are fiduciary in nature. Trust, estate, custodial (UGMA/UTMA), and guardian accounts are all fiduciary.
